Given the fact that I am new to baking gluten free, I decided to buy a prepackaged GF flour to start. This is what I have been using.
Ingredients include: garbanzo bean flour, potato starch, tapioca flour, whole grain sweet white sorghum flour, fava bean flour.
I can find this at my health food store and even at walmart now, so until I get a better grasp on different flours and flavors, this is what I'll use (and so far seems to be working fine).
The one thing that I have noticed...I am a HUGE fan of tasting the batter before baking. This flour makes the batter taste BITTER! Don't lick the spoon when using this stuff! Everything tastes fine when it's done baking, but not before ;-)
